CUSHION-TIRE WHEEL.

Patented Dec. 27, 191%.

Application filed February 2, 1910. Serial No. 541,441.

- wheel and more'particularly to one in which the tire is made up of sections which may be separately removed from and attached to the wheel. o

The object of my invention is to improve the manner of securing theeections to the wheel so that the'construction will be simple and effective in operation.

In the accompanying drawin which illustrate'one form of wheel ma e in acoordance with my invention Figure 1 is a cross section; Fig. 2 is a side view and Fig. 3 is a detail view of one of the retaining members.

Like marks of reference refer to similar parts in the several views in the drawin 5 represents the folly of the wheel w ich may be of the usual form and is preferably made of wood. Surrounding the folly 5 is the rim 6. The rim 6 differs from the usual rim in having its sides 7 project beyond the sides of the telly 5 as shown in Fig. 1. Seated on the rim 6 are the sections forming the tread of the tire. These sections are formed of rubber or other suitable resilient material and each consists of a body 8 and a base 9. The ends of the bodies 8 are somewhat shorter than the bases 9 so as to leave spaces 1O beyond the ends of the sections as shown in Fig. 2. These spaces 10 allow the material of the tire to flow as the tire is compressed and thus obviates the forming of a ridge in front of that portion of the tread which is in contact with the ground. Passing transversely through the sections of the tire are a number of rods 11. These rods project somewhat beyond the base of the sections and the base of each of the sections is provided with lateralprojections 12 which form seats for'tbe ends of the rods 11.

13 designates the retaining members. Each of these members 13 is provided with a ections 12 of the base of the. section and also pocket 14 adapted to receive one of the pro the ends of the rods 11. The pockets 12 are slightl less in depth than the rejections 12 of t e bases ofthe sections as is shown at the right hand 6f Fig. l. The retaining members 13 are secured in position by means of bolts 15 passing down through openings 16 in the retaining members 13 and through the projecting sides 7 of the rim 6. The bolts 15 are engaged by means of nuts 17. By tightening t e nuts 17 the bolts 15 draw the retaining members 13 down so as to compress thebase of the tireand hold it firmly in position against the rim as is shown in the right hand side of Fig. 1.

It will be seen that while my construct-ion is simple it is veryeifective inasmuch as 1t holds the sections of the tire firmly against the rim so as to avoid any possibility of movement and the consequent working of the rods loose in the sections. Furthermore, the construction is such as to readily allow an section to be removed and a new section so stituted without disturbing any of the remaining sections of the whee As each of the retaining devices is'entirely independent of the others the tire may be firmly held in place even if the wheel becomes slightly dcformed in shape as may often occur from lo n use.

avin fully "described my invention, what I caim as newand desire to secure by Letters Patent of the United States is:

1. The combination'with the rim of a 0 said retaining members being provided with a pocket closed at both ends and adapted to receive one of said projectionsmnd means for removably securing said retaining members to the rim of the wheel.

'2. The combination with the rim of a wheel, of a tire of resilient material formed in sections, each of saidsections being-pro vided at'its base with a pair of lateral projections, transverse rods passing through the base of each section, a pair of independent sets of sectional retaining members, one set 7 said pockets havingrecesses in their ufifjier parts to receive the'ends of said trfi'isi epse rods, and means for removably securing said reta i ing'members to the rim of the Wheel.

' In testimony whereof, I have hereunto set my hand and affixed my seal in the presence of the two subscribing witnesses.
